I have decided to upgrade from my Sharp 80 inch and have narrowed te choice to the 82" Q8F or the75" Q9F. The current price is the same and although I like the extra real estate of the 82" I also like the one connect feature on the 75 inch series. I will be mounting it on the wall as my current unit is but I have experienced the difficulty of adding or changing cables on a wall mount. My research indicates the two are virtually identical with the exception of the screen size and one connect system. Please let me know your thoughts and if I have missed any features that would make one better than the other. Thanks in advance for your comments.
